Who do you suppose is really running the U.S. government these days?

It ain't Sleepy Joe. If you look up "figurehead" in the dictionary, you see a faceless avatar labeled with his name.

I think there's a "central committee" in charge now, just like they (and I mean THEY) had Back In The USSR (sorry, Beatles).

Probably an inner committee of "Ministers," and then an outer commitee of "Deputy Ministers."

All we can do is guess, but my guesses for Inner Central Committee are these:
George Soros
Barack Obama
Bernie Sanders (maybe - he's actually elected, so maybe not)
Jeff Bezos and probably 3-4 other tech/media people
Xi Jinping and probably a couple other Chicoms
Vlad Putin and probably a couple other Russkis
The entire "Squad" (though they're also elected, so maybe not)
Maybe Tony Fallacy, though he's more of a mouthpiece
Lex Luthor, Bane, and maybe the Joker (well, they're all jokers)
(And the joke's on US)

Everybody else you'd imagine for this Committee are probably on the larger Outer Committee, or Politburo, or whatever they call themselves. They'd include Kommie Harris, Michele Obama, Chuck U. Shumer, Crazy Nancy, Gretchen Widmer, Anyone Named Cuomo, Gavin Nuisance, Hillary, Bill, Chelsea, blah blah blah.

What are your guesses?

I'm guessing President Select Sleepyhead isn't anywhere on these lists at all.
